Abstract: L'invention est constituée par un système et une méthode de mise en commun d'un groupe d'agents (24, 26, 34) dans une opération de traitement d'appels téléphoniques de façon à ce que ces agents soient utilisés efficacement. Les téléphones des agents du groupe sont couplés à un certain nombre de lignes de communication d'arrivée dédiées (14) par un distributeur d'appels automatique (DAC) (18). Les téléphones d'un autre groupe d'agents sont couplés à un certain nombre de lignes de communication de départ dédiées (16) par un composeur automatique (30). Ces téléphones peuvent être couplés à ce composeur directement ou par l'intermédiaire du DAC. Dans une autre concrétisation de l'invention, les agents peuvent appartenir à un groupe unique et être tous disponibles pour le traitement des appels d'arrivée et de départ. Les agents sont transférés du traitement des appels d'arrivée au traitement des appels de départ quand l'indicateur de réponse des agents pour les appels d'arrivée se trouve sous un seuil prédéterminé. Le transfert des agents vers le traitement des appels de départ se fait par un appel interne du composeur automatique qui est transmis à un agent par l'intermédiaire du DAC. Ce transfert est annulé à la fin de l'appel interne et non à la fin des appels de départ individuels pris en charge par l'agent transféré.

Title: Gas cartridge
Inventor: SAXBY MICHAEL ERNEST
IPC: F41B11/72
Filed: 1994-08-15
Granted: 1998-09-01
Abstract: A cartridge has a case comprising a body (10) housed telescopically within a sleeve (14). The body encloses a main chamber (21) which contains gas under pressure, and a valve mechanism for venting gas from the chamber (21) into an expansion chamber (61). The pressure of the gas in the expansion chamber causes the body (10) to move rearwardly relative to the sleeve (14) to apply a force to the breech block of the weapon in which the cartridge is used, thereby to initiate the reloading cycle. Gas is vented from the expansion chamber to eject a projectile when a spigot (51) projecting from the body is withdrawn from an aperture (53) in the end wall of the sleeve.
